S-(Carboxymethyl)-L-Cysteine ​​CAS 638-23-3 (Carbocisteine) Mayeso 98.5~101.0%

S-(Carboxymethyl) -L-Cysteine, ikauma, imakhala ndi osachepera 98.5 peresenti komanso osapitirira 101.0 peresenti ya S-(Carboxymethyl) -L-Cysteine ​​(C5H9NO4S).
Kufotokozera: Makhiristo oyera kapena ufa wa crystalline, kukoma kwa asidi pang'ono.
Kusungunuka pang'ono m'madzi, kosasungunuka mu ethanol ndi glacial acetic acid ndi ether.Amasungunuka mu dilute hydrochloric acid ndi sodium hydroxide TS.
Kusungunuka (H2O, g/100g): 0.13 (20℃)
Chizindikiritso: Fananizani kuchuluka kwa mayamwidwe a infrared a chitsanzo ndi njira ya potaziyamu bromide disc.
Kusinthasintha Kwachindunji [α]20/D: Chitsanzo chouma, C=10, pH6.0.Mukamaliza kuumitsa, tengani pafupifupi 5g yachitsanzocho.kuyeza bwino, sungunulani mu 20ml yamadzi ndi sodium hydroxide solution (13→100).Pambuyo pH kusintha kwa 6.0 ndi 1mol/L kapena 0.1mol/L hydrochloric acid TS, ndiye kuwonjezera madzi molondola 50ml.
State Solution (Transmittance): 1.0g mu 10ml wa 1mol/L NaOH, spectrophotometer, 430nm, 10mm selo makulidwe.
Chloride (Cl): 0.36g, A-2, ref: 0.40ml ya 0.01mol/L HCl

Ma Amino Acids ena: 0.2mol / L NaOH, kuyesa Chitsanzo: 75μg, B-2-a control;S-(Carboxymethyl) -L-Cysteine ​​​​0.15μg.Pambuyo pa njira iliyonse yothetsera vutoli, mbaleyo imapangidwa nthawi imodzi
Kutaya pa Kuyanika: pa 105 ℃ kwa maola atatu
Zotsalira pa Ignition (Sulfated): AJI Test 13
Kuyesa: Zitsanzo zouma, 180mg, 0.1mol/L HCLO4 1ml = 17.920mg C5H9NO4S.Sungunulani pafupifupi 180mg yachitsanzo, chowumitsidwa kale ndikuyezedwa molondola, mkati3ml ya formic acid, onjezerani ndendende 15ml ya 0.1mol/L perchloric acid, ndi 50ml ya glacial acetic acid, ndi titrate owonjezera perchloric acid ndi 0.1mol/L sodium acetate,kudziwa mapeto potentiometrically.Chitani chitsimikiziro chopanda kanthu, ndikuwongolera koyenera.ml iliyonse ya 0.1mol/L perchloric acid ndi yofanana ndi 17.920mg ya C5H9NO4S.
pH: 1.0g mu 10ml (madzi odzaza amadzimadzi)
Malire osungira ndi momwe amasungira: Zotengera zothina zosungidwa pamalo otenthetsera mchipinda chowongolera (zaka 2).
